Abstract:
Posterior sternoclavicular joint dislocation is a rare injury requiring prompt diagnosis as it has been associated with the compression of the subclavian and brachiocephalic arteries. We report the case of a 27-year-old male presenting with altered mental status and left hemiparesis found to have life-altering neurologic damage caused by severe orthopedic injury after a fall while intoxicated. Imaging revealed a posteriorly displaced right medial clavicle with surrounding hematoma compressing the brachiocephalic artery causing local thrombus formation and distal embolization, ultimately resulting in malignant cerebral infarction. His hospital course was complicated by cerebral edema requiring decompressive craniectomy, hemorrhagic transformations, brachiocephalic pseudoaneurysm, and the development of remote embolic ischemic infarctions.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
